TORONTO, ONTARIO--(Marketwire - Dec. 14, 2009) - Macusani Yellowcake Inc. ("MYI" or the "Company")(TSX VENTURE:YEL) is pleased to announce that channel samples taken from underground adits at the Pinocho zone of the Kihitian Property on the Macusani Plateau in Peru, have returned extensive high grade uranium with average values of 0.554% U3O8 (11.09 lbs U3O8 per ton).

A total of 97 channels samples were collected along the adits with results ranging from trace to a high of 4.67% U3O8 (103 lbs U3O8 per ton). Greater than 25% of the samples returned over 0.45% U3O8 (10 lbs U3O8 per ton). Details of the channel sample results are shown in the table below.

MYI's CEO, Peter Hooper, stated that "These exciting results have established priority drilling targets that could expand the resources already controlled by our Company on the Macusani Plateau."

The uranium mineralization in the Pinocho Zone is mainly contained in veins and anastomozing veinlets hosted within rhyolite tuff. There is consistently a central zone that ranges between 15 cm and 1 m in thickness that represents the high-grade core of the uranium enriched mineralization. The uranium grades in the veins can run from several lbs/ton to as high as hundreds of lbs/ton.

The adits at Pinocho total approximately 194 m in length and were sampled every three meters, on the left wall, from the floor to the ceiling throughout the entire length of the workings. The workings range in height from 1.10 to 1.85 meters and in many cases due to their limited height, sampling of the hanging-wall and foot-wall alteration zones was not possible. The mineralised structures exposed within the adits are open in all directions.

In total the Kihitian Property contains approximately 900 metres of adits developed by IPEN, the Peruvian Nuclear agency, in the early 1980s. These adits were dug into one of the largest radiometric anomalies on the Macusani Plateau. MYI acquired the Corachapi and Kihitian properties from Ram Resources Limited of Australia (formerly Contact Uranium Limited) earlier this year (see Press Release dated June 30, 2009).

The samples averaged 2-3 kg per sample and were sealed in a plastic sample bags for transportation with MYI personnel. Two standards were included within every 25 samples. The samples were sent to CIMM Labs in Juliaca for sample preparation with representative samples of 250 grams then sent to Lima to be analysed by ICP-MS techniques for uranium and a larger suite of elements.
